[svn-r15868] Description:

	Correct a minor error in file free space allocation which was affecting
the 'multi' VFD and preventing some tests from fully working with it.

	Wholesale revisitation of all the places where tests were disabled
with various VFDs and remove or correct all these so that _only_ the tests
which _really_ can't work with particular VFDs are skipped during a
'make check-vfd' test.

Tested on:
        Mac OS X/32 10.5.5 (amazon) in debug mode
